FILE-DRIVING- MECHANISM.

Specification of Iietters Patent.

Patented Mar. 9, 1915.

Application filed May 5, 1914. Serial No. 836,395.

employed for vertical pile driving or for ac-' curately driving a pile or piles at an angle to the vertical.

It has for. a further object to'provide a device wherein the height of the driver frame may be adjusted so that piles of different lengths may be used in connection with the mechanism without decreasing the efliciency or lessening the effective impact of the driving ram.

It further consists of other novel features of construction all as will be hereinafter fully set forth.

For the purpose of illustrating'my invention, I have shown in the accompanying drawings one form thereof which isat present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is'to be understood that the various mstrumentalities of which my invention consists can be variously'arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

In the drawings :Figure 1 represents a side elevat ion of a pile driver embodying my inventlon; Fig. 2 represents a vertical section of a portion of the device; Fig. 3

represents a side elevation of the top portion of the boom arranged for use as a hoisting mechanism; Fig. 4 represents a plan of the pile driver; Fig. 5 represents a transverse section showing the auxiliary guy frame; Fig. 6 represents a section on the line ww of Fig. 1; and Fig.7 represents a section on the line y l of Fig. 1.

1 designates a pair of beams forming the main supporting base of the device and which are adapted to be firmly secured upon a suitable su port, such as a scow 2 or float, although it will be understood that this may be replaced by any suitable form of support. These beams 1 project beyond the support 2 and form what may be termed a throat to receive the pile driving mechanism and through which the pile to be driven is adapted to pass.

3 designates a boom suitably pivoted at at its upper end trunnion plates '5 adapted to receive a pin 6 which passes through the apertured plates or ears 7 fixed to a suitable portion of the driver frame. This driver frame consists of a pair of beams 8 suitably spaced apart and braced at intervalsbythe tie braces 9.

1O designates guides or guide rails secured to the beams 8 and provided with rails or monkey or ram 12 which is slotted at the sides'for the purpose readily apparent.

The beams 8 are also preferably braced by the truss 13 which is further reinforced by stay-rods 14, the latter tying the truss to v the main pile driver frame.

15 and 16 designate sheaves located respectively at the upper and'lower ends of the driver frame and about which the rope ram 12. It will also be noted that a guide pulley 18 is mounted between the plates 5 and is free to rotateupon the pin 16 in or der to properly guideand prevent. displacenected to the ram 12 by any suitable type of mechanism such as a striker-0E or the like for releasing the ram, but as this connecting means forms no part of the present inventype of fastening between the ram and the said cable. 7 p

.19 designates. a ladder. frame having rounds or step bars 20,- all of which structure is fixed t0 the driver frame and enables the operator or user to gain access to the different parts of the frame for purposes of repair or adjustment. 21 designates a pair of masts forming with the brace bars 22 an A-frame, carry-" ing at'the upper end suitable supports for a clevismember 23 which carries a pulley, block 24 about which a cable 25 passes for raising and lowering the boom 3. A similar the lower end where it passes about a fixed 110 4 to the supporting structure and carrying 7O .guides 11 adapted to cooperate with the p or cable 17 passes for connection with the s5 ment of the cable 17 The cable 17 is contion I have merely shown a conventional block mechanism 26 is suitably supported at the upper end of the boom 8 and the cable pulley 27 to a suitable hoisting mechanism not illustrated.

28 designates a tie-rod connected. at one end to the upper portion of the A-frame, and at its lower end to the fixed support,

whereby the frame and its adjuncts are fixedly secured in operative position.

By reference to Fig. 6 it will be seen that tive guide members 10, and extend laterally therefrom, each having a recessed portion to receive the bar 31 which serves as a holder.

to prevent the pile from being displaced. It will further be noted that the lower extremity of each of the beams 8 is provided with a plurality of apertures 32 to receive a fastening bolt 33 or like device which passes through the respective beams 1 and thus maintains the driver frame properly located withinthe throat. These apertures 32 form a means for adjusting the driver as to 7 height and as the bolts 33 form pivots, the said frame when once located in the desired opening 33 may be swung to any desired angle so that the pile may be driven .in a position other than the vertical if desired. This swinging of the frameabout the pivots 33 is accomplished. by raising or lowering of the boom 3 through the lower devices controlling the cables 25. V In Fig. 3 I have shown a modified form of a device wherein by employing a sheave 34positioned at a suitable point on the boom 3 the cable 17 maybe passed thereover and its'free end attached to a dredgingdevice, clam forks or like apparatus.

In, the operation of the device the A- frame. and its supports, togetherzwith the boom and throat beams, are suitably fixed in position adjacent the point where the piles .are. to be driven," after which the driver frame is located for height by adjusting .the bolts 33 in the proper openings 32. If the piles are to be driven vertically the boom .3 is power actuated to raise the frame and theram being raised by power, released and dropped by gravity. In. case thepiles are to be driven. at an angle the driyer frame, after a pile has been placed in position within the frame, maybe shifted to the desired 5 angle by swinging the boom until it is prop erly adjusted andwhere it maybe held accurately during the pile drivingoperation.

It will now be apparent thatI havedevised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description,- and while I have in the present instance shown and described the preferred; embodiment thereof which has beenfound in practice to give satisfactory andreliable results,=it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of: the invention or sacrificing anyof its advantages.

I claim 1. Ina device of the character stated-,1 a

base, a driving frame pivotally connected to said base, means for pivotallyconnecting said frame at difie'rent points longitudinally thereof to said base .whereby it may be longitudinally adjusted, a .boom connected to 1 one end of said. frame, a ram mounted for 1 sliding movement on said frame, power. transmitting means for raising and lowering the upper end of said boom to raise and lower the upper endof said frame to Vary. the angular position thereof relative to said base, a fixed frame to which the power actuating means is connected and .meansforw mg. frame having ,one vend positioned" within said throat, pivotal connections between said base and said frame whereby the datter maybe swung, forwardly and rear-' wardly, said pivotal connections being :adjustable, guides on. said. frame, a ram mounted to slide on said guides, a transversely arranged bar adjacent zone endof said frame for maintaining a pile in. position' within the path of movement of @said ram regardless of the angularposition of said frame, said bar being movable from one position to another so that a pile may.
